A nurse is conducting a prenatal education session for expectant parents. Which maternal condition should the nurse identify as a risk factor for congenital heart diseases?

A) Incorrect. Not all congenital heart diseases resolve on their own. While some may improve over time, it is essential for the client to follow their healthcare provider's recommendations for monitoring and treatment.

B) Incorrect. While breastfeeding has many benefits for infants, it may not directly impact the congenital heart disease. The nurse should focus on educating the client about managing the specific heart condition.

C) Incorrect. Avoiding vaccinations and routine check-ups is not recommended. Regular check-ups and vaccinations are crucial for overall health, and the healthcare provider will guide the client regarding any specific precautions or modifications needed due to the heart condition.

D) The answer is D. Clients with congenital heart diseases are at increased risk of infections, so it is essential to educate the client about infection prevention measures, such as limiting contact with other children during times of increased risk.

A) This option is incorrect. Family history of congenital heart diseases is a significant risk factor. If a close family member has had a congenital heart defect, the risk of recurrence in subsequent pregnancies may be higher.

B) Correct answer. Exposure to certain infections during pregnancy, such as rubella (German measles), can increase the risk of congenital heart diseases in the baby. Rubella is known to be teratogenic, meaning it can cause birth defects.

C) This option is incorrect. While a healthy lifestyle during pregnancy is important for overall maternal and fetal health, it is not the primary risk factor for congenital heart diseases.

D) This option is incorrect. While genetic factors play a significant role in the etiology of congenital heart diseases, there are other identifiable risk factors, as mentioned in option B.
